insulating floor over unfinished basement (vapor barrier?)
Not sure if this should be in the floor forum or an Insulation forum but here goes anyway. I have a tile floor in the kitchen over an unfinished section of basement. The basement drops to 55 degrees in the winter obviously making my kitchen tile floor cold. I have very easy access to put some R13 fiberglass up into the joists below the kitchen footprint. My question is about CONDENSATION. I'd rather have the paper side facing the basement (which is a bitter nice to look at than fiberglass). With the 55 degrees basement and 70 degree kitchen floor do i have to worry about condensation being created at all? i'm over-worrying about that right?
Paper side of insulation should usually be on the warm side, if i push it up into the joists i'm having the paper on the cold side. I don't want to be creating a moisture issue by doing this. but its only a 15 degree differnce at most.. does moisture form at 15 degree difference?
